> The `jdk/jshell/ToolSimpleTest.java` randomly fails, the reason is this: when indexing the bootclasspath/`PLATFORM_CLASS_PATH`, `$JDK_HOME/lib/modules` is typically there, but it can't be opened as a FileSystem, and the exception is sent to the debugging facility. The debugging facility typically does nothing, but in this test contains a test case that enabled debugging, and if the order of things is that the debugging is first enabled, and then the `ProviderNotFoundException` is reported, the test fails.

Suggestion:

                !isJRTMarkerFile(path)) {  //don't directly index lib/modules
